Start Sit: Clinton Portis

From Will Carroll's Black & Blue Report at Football Outsiders:

"Clinton Portis had a bad concussion. Jim Zorn said he was knocked out and after the game, Portis had no memory of the incident. Right there, at best, Portis is looking at a Grade II concussion, though the time of unconsciousness isn't always the best indicator of how severe the concussion is. As Dr. Jorge Cantu, one of the leading experts in the field, explained to me earlier this year, the only way to grade a concussion is after all the symptoms have cleared. (Cantu should know -- the grading scale is named the Cantu scale because he invented it.) Portis will undergo ImPACT testing and other medical tests to help determine when he'll be back. We'll have to watch to see if he's exhibiting any symptoms at the end of the week, but it's very unlikely that he'll play this weekend, leaving the carries to Ladell Betts."

The strikethrough is mine. I have no idea what the Redskins will do at RB, but there is little reason your fantasy team should be dependent on that pie-in-the-sky gamble.
